Specification of Letters Patent. Application fi1ed'November"19,,1907. Serial No. 402,796.

I Patented Oct. e, 1908.

Be it known that I, NEKOLAI DAHL, merchant, a citizen of the Kingdom ofNorway, residing at Fjordgaden 82, city of Trondhjem, Norway, have invented a new and useful Improvement in Box-Fasteners; and

I do hereby declare'the followingto'be a full,

- clear, and exact description'of the same. i

My present invention has for its object to provide a closing device for cases and the ke and is especially applicable for such packing-cases which are intended for shipment of herrings and fish in great quantities. Such cases are generally used over again many times. On account hereof the re-.

spiking hitherto used is very timewasting and at the same time very destructivetothe case.

3 In orderthat my invention may be clearly understood and readily carried into effect, I

will proceed to describe the same with refer-;

ence to the accompanying drawing, in which Figure 1 is a side-elevation of a case with a closer constructed according to my inven tion, the cover being removed. Fig. 2 illustrat'es the same, the cover being laced in position. Fig. 3 is anend-view o the case shown in Fig. 2 andFig; 4 a side view of the case sealed. Figs. 5, 6' and 7 are front, side.

' and rear views, illustrating theclosing device proper. Fig. 8shows a modified'form for carrying out my invention.

The closing device consists of a springy steel plate a having ,a metal plate -b pivoted to it' by means of a pin or nail c+ on which the two plates may turn in relation to each other; The metal plate b is atthe' top bent at aright'angle so as to form a hook .d. The deviceitself is secured to the side of the case near one of its ends by means of a wood-screw e on which it can turn. When the case is open and the cover removed, theclosing device is forcedsomewhat out to the 'side'and turned towards the middleof'thecase (Fig. 1)..

v I neath the fixed part of the to (or into slots made in the walls of the case) t e cover g will beretained, and as the cross-bars of the cover engage the other three side walls of the case, the cover will also be secured against horizontal movement.

The other end of the cover is now fastened by turning back the closing devices till the hooks g Fproject over the top surface ofthe cover ig. 2). The closing device hasnow to be turned as far aspossible to one side (in the figure to the left), which is done by pushing the plate parallelly sidewise, the turning on its pivot e.

late a ereby the hook d. is caused to press the cover down and keep it close on to the case. The closing device and at the same time the case are now very easily sealed by inserting a label between the plates .a and b, which can be done because the steel plate -a is flexible. .Then the label is fastened by means of pump-tacks. In order to protect the hook-0Z itis received into a recess made in the top surface of the cover.

The case is opened by removing the label and turning the closing devices aside (in .the drawing to the right), at the same time bending the plates a outwards so that the hooks d will bear upon the outside of the case. I

Eachcase is furnished with two closingdevices.

In the form shown in Figs.14, the cover g extends close to the left end Wall of the case.

said wall, part f having recesses 7c continuing the recesses 7r in the cover described above. This modified form is shown in Fig. 8, in which the case may be opened by moving the hooks b to the left so that the parts d are received into the recesses 7c, and the cover may freely be removed. The opening and closing of the case is by this form ofthe closing device easier than by the device, shown in Figs. 1-4.

Having-now described my invention, what I claim as new and desire to secure by Letters Patent is y In closing device for cases and the like the combination of a springy metal plate the lower end of which is ivoted to the outside of the case wall, and a ook-shaped part piv- In testimony whereof, I have signed my name to this specification 1n the presence of two subseribmg witnesses.
